Hanger brackets 41 V are .pivotallyiinounted upon the shaft 32 passes."

operated and therefore itv is not'necessary to remove the sharpening attachment when a the ensilage cutter is in use unless it is desired to transfer the attachment from one machine to another or for the purpose of making repairs to the sharpening attachment.

' Aycarriage'43 is slidably mounted upon the track 33 and is intended to be moved v transversely across the ensil'age cutter so that the grinding stone may be moved longitudinally along the cutting edges of the blades 19. A bushing 44 is placed inthe carriage 43 to take up wear caused by frictional engagement with the track A bearing- 45 through which thefshaft 46' snpasses'is provided with hinge ears 47 whi'c'h are pivotally connected "with the hinge cal [48 of carriage 43 by means of'a pivot pin 549. A yoke 50 'is placed upon the pin 47' withits arms 51 engagingthe upper and lower edgesof one of the hinge? ears 47.1 Fromthelower .end portionofthe yoke 50 there extends anarm 52 which has its end portion bent to form a'finger 53 with which Y I a rod54 is pivotally connected. It will thus be. seenthat by means of the rod.54,'fthe bearing through which the shaft 46-passes may be pivotally moved with respect to the carriage 43 thus bringing the grinding stone '55 into and out of engagement withthe cutting blades l9. A collar 56 is placed upon the shaft 46 between the bearing 45 and bevel gear 57 and is provided ,witha liner sleeve 58 which extends int o the bushing 59' placed in the bearing 45. From the collar 56 there extends the yoke arms 60 which have their upper ends formed into bearings 61 slidably mounted upon the shaft 62.

This shaft 62 whichis connected with the shaft 32 by means of a universal joint 63 is provided with a longitudinallyextending groove 64 so that the bevel gear 65 may be keyed to the shaft 62 and thus permitted to slide upon the shaft 64 but at the same time caused to rotate with the shaft 62;

The operation of this attachment is as followsz The frame of the attachment is 7 connectedwith the frame of the ensilage -cutter-by securing the bearing clamp 38 about the shaft--14 and then connecting the standard 34 with the bearing 35. After the frame of the; sharpening attachment is in .place the arm or bracket 21 is placed in en= gagementwith the bolt 22 and thearm 21 either raised to move the pulley 29 out of wing nut 24'wi1l,' of course, be, ig 113 engagement with the belt 15 or lowered so. 7'

as to'hold the'braoket 21 in" the adjusted" position; When this device is being operx ated, theipulley 16'will be released from the I shaft 14 so that the'shaft will be rotated and thecutting knives will thus be prevented from'rotating when it is desired'to sharpen the same. 'When the pulley wheel- 2 9 is in The relatively large stone 55 and it will thus be seenthat'the grinding stone 55 will be very rapidly rotated; The cutting blades 19 are successively brought into the position shown in Fig.1 sothat'the grinding stone can engage the:

cutting edges; of the blades and the carriageis then moved along the track 33 to cause the grinding 'stoneto travel froml'one end of the cutting blades'to the other. The

carriages moved'by means of'the rod 54 which may also be used for rockingthe bearing 45 upon the pivot pin 49 thus causing the grinding stone to bear against thef'cutting edge of the blade with as much pressure as desired After the. blades of the knife'have been sharpened, the carriage may be moved to the right hand end of the track so "that the grinding stone will not'be liable to strike the blades of the revolving knife. The

frameorbracket 21 can now be raised and held in the raised position by the clamping nut 22 and; the pulley wheel 29 will be out of engagement with the belt 15. The pulley the shaft 14 and the ensilage cutter is ready for operation. This attachment may be left upon the machine while using thesame and can be removed and put away for safe keeping wheel 16 is now again securely connected with when the ensilage cutter is no longer needed.

This attachment should be left upon the machine while using the'same since the knives of the ensilage cutter require sharpening at least twice a day injorder to keep them in good condition and'therefore it would not be convenient to connect the sharpeningat-j tfachmentflwiththe machine every time the V knives needed sharpening. It shouldalso be noted that with this attachmentitis not" necessary to remove the cutting knives from the ensilage cutting machine and therefore the knives do not have to be adjusted after being sharpened.
